The \"HAL\" name comes from the Hall effect principle the unit relies on to read trigger input with exceptional precision.\u003c\/p\u003e\n\u003cp\u003eEven before you factor in the electronics, the base platform is well specced: a \u003cstrong\u003e6.03 mm inner barrel\u003c\/strong\u003e for tightened accuracy, paired with an adjustable Hop-up chamber fitted with quality rubber. Spring swaps are handled through the \u003cstrong\u003eESA quick spring change (QSC) system\u003c\/strong\u003e, so you can move to a stiffer or softer spring without ever pulling the gearbox from the receiver — the whole job is done through the buffer tube. The gearbox itself is reinforced to handle springs rated up to M120, per Specna Arms' specifications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat the HAL ETU™ unit brings to the table:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHall-effect magnetic sensor for trigger detection\u003cbr\u003eActive braking system\u003cbr\u003eBinary trigger function (fires on both pull and release)\u003cbr\u003e5-stage adjustable trigger sensitivity (20%–100%)\u003cbr\u003e6-stage adjustable pre-cocking\u003cbr\u003eCustom SEMI modes: semi, binary, AUG-style, delayed sniper\u003cbr\u003eCustom AUTO modes: full-auto, semi, 3-round burst, 5-round burst\u003cbr\u003eTrigger-based programming — no extra tools needed\u003cbr\u003eLow battery alert\u003cbr\u003eBrushless motor compatible (works well with units like the Specna Arms Dark Matter or Warhead)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eExterior Build\u003c\/strong\u003e\u003cbr\u003eThe nylon body is finished to a high standard — matte texture, realistic detailing, and fiberglass reinforcement that keeps it both tough and light in the hand. Metal shows up where it counts: the outer barrel, ejection port, and pins are all steel or machined metal, not plastic substitutes.\u003c\/p\u003e\n\u003cp\u003eBuilt on the familiar AR15 ergonomic platform, the layout feels intuitive from the first grip — controls fall naturally under your fingers and the balance suits fast handling.
